Match ' QRT' in the comment as well as the existing QRT variants

[alanhargreaves]

What does this PR do?

Adds another variant of 'QRT' to match a spot comment in POTA, SOTA and WWFF.

..., and of course just after creating the PR, I notice someone in WWFF put 'qrt' in their comments.

I deliberately chose to match against 'QRT', so we would pickup comments that had an end of string, or some kind of punctation following 'QRT'.

I noticed a SOTA spot being shown when the comment string was "Now QRT many thanks chasers".

Thanks for catching this — filtering QRT in any position in the comment is the right call.

A couple of notes on the implementation:

1. Redundant .toUpperCase() — comments is already uppercased on the line above (const comments = (...).toUpperCase().trim()), so the .toUpperCase() calls in the condition are unnecessary.

2. includes(' QRT') is a bit too broad — it would match any word starting with QRT (e.g. hypothetical " QRTZ"). More importantly, a single regex can replace the entire chain of conditions and handle all positions/punctuation cleanly:

const comments = (s.comments || '').toUpperCase().trim();
if (/\bQRT\b/.test(comments)) return false;

This covers standalone QRT, QRT , QRT,, QRT, Now QRT many thanks chasers, etc. — all in one line, with word-boundary safety.

Applies to all three files (usePOTASpots, useSOTASpots, useWWFFSpots).

Good point. I also eliminated the extra variable.
